MEITALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters PatentNo. 739,637, dated September 22, 1903. Application filed July 25, 1903. Serial No. 166,955. (No model.)

To aZZ whom it may concern.-

Be it known that we, DANIEL N. AVEY and GUY T. HASTINGS, citizens of the United States, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements tallic tie-boxing provided with downwardly-' extending flanges to securely hold the tie from longitudinal movement and in the provision of clamping means for holding rails to the boxing.

The invention consists, further, in various details of construction and in combinations and arrangements of parts, which will be here inafter fully described and then specifically defined in the appended claims.

Our invention is illustrated in the accompanying drawings, in which similar letters of reference indicate like parts in the views, in which-- Figure l is a top plan view of a tie, showing means for holding the rails thereto. Fig, 2 is a central longitudinal section through the tie and the clamping means. Fig. 3 isa detail view showing the means for clamping the rails for holding the same to the boxing or tie.

Reference now being had to the details of drawings by letter, A designates a hollow tie having an aperture A in its top and an openin g A in the bottom thereof, the ends of said opening A terminating in flanges A which project at right angles from the tie and are adapted to form anchorage means for the tie to prevent the same from movement when embedded in the ballast of a railway. Integral with or secured to the top of the tie are stationary curved lugs B, designed to engage over the flange of a railway-rail, each ofsaid lugs cooperating with a movable clamping member G on the opposite flange of the rail to hold the latter to the tie. Each of said movable clamping members 0 has a shank portion extending through an aperture in the top of the tie and having a slot adapted to receive a wedge-shaped member D. The upper end of each wedge-shaped member when inserted in the slot of the shank portion of the clamping member contacts with the un der surface of the top of the tie, and the inner end of each clamping member has threads which are adapted to. engage threads in the apertures formed in the ends of the turnbuckle E, whereby as said turnbuckle is rotated in one direction the two wedge-shaped members will be drawn toward each other, thereby causing the movable clamping members to be drawn down securely against the flanges of the rails. The reverse movement of the turnbuckle will cause the wedge-shaped members to be thrown in the opposite direction, which will release the clamping memhere.

From the foregoing it will be observed that by the provision of atie embodying the features of our invention the latter will be socurely held from lateral or longitudinal movement by reason of the flanges on the under side thereof, while the rails will be securely held to the tie and clamped or released by means of the turnbuckle mechanism, thereby what we claim as new, and desire to secure by Letters Patent, is-

l. A hollow railway-tie" having flxedz lugs 7 adapted to engage the flanges of; rails, movable clamping-jaws passing through the top of the tie, wedge-shaped members engaging slots in said members, and a turnbuckle having threaded engagement with the ends of said wedge-shaped members, whereby the lat-. ter may be drawn against the flange of a rail,

as the turnbuckle is rotated, as set forth.

2. A hollow metallic railway-tie having an aperture in its top and bottom, flanges at the ends of the aperture in the bottom of said tie, fixed lugs on the top of the tie, elampingthreaded ends of said wedge-shaped memjaws extending through apertures in the tie, here, as set forth.

wedge-shaped members passing through elon- In testimony'whereof we hereunto affix our gated slots in said members and adapted to signatures in presence of two witnesses. 5 frietionally engage the upper surface of the DANIEL N AVEY top of a 116 and draw said members securely I. V T. HASTINGS.
